Here's a Tank you don't see every day...
18k gold with integrated leather strap. The pictures are from the Monaco Legends Auction catalog for the up coming June auction. ...
For some reason
I find the leather strap very attractive in an almost erotic way, waiting for the watch to be undressed!
Probably gonna be hard to stick that on a NATO during the hot sticky summer months. lol
I'm guessing Cartier had replacement straps at one time.
